Cheap car alarm system

Types of Cheap Car Alarm System

There are several types of cheap car alarm systems to meet different market demands. They include:

• Active car alarm

  Active car alarms are manually controlled by the driver. The driver needs to activate and deactivate the system using a remote key fob or a separate switch. When unauthorized access is detected, such as a door being opened without permission, the active alarm system responds by sounding a loud siren or horn, drawing attention to the situation. These alarms are straightforward and are often used in less expensive systems.

• Passive car alarm

  Passive car alarms are automatically activated and deactivated with the vehicle's ignition system. The driver does not need to do anything extra when entering or exiting the car. The system uses a signal from the key fob or the vehicle's ignition to determine whether the car is being accessed with authorization or not. If unauthorized access is attempted, the passive alarm triggers, alerting everyone nearby. Passive alarms provide convenient, hands-free operation, making them popular in modern alarm systems.

• Immobilizer alarm system

  Cheap car alarm immobilizer systems prevent unauthorized access to the vehicle and prevent it from starting. It does this by interrupting the essential electrical circuits, such as the fuel pump or ignition system. If the alarm is triggered, the immobilizer will prevent the engine from starting, effectively stopping potential thieves from driving the car away. Many modern cheap car alarm systems come with built-in immobilizers, providing an extra layer of security. Some countries have even made it a legal requirement for all new cars to be fitted with immobilizer systems.

• GPS tracking systems

  GPS tracking systems are designed to track and locate a vehicle in real time. They are not activated or deactivated like traditional alarm systems, but they monitor the vehicle's movement continuously. If the vehicle moves outside a predefined area or if it is moved without authorization, the GPS tracking system sends alerts to the owner, allowing them to take action. Some advanced systems can be monitored through a mobile app, providing live location updates and additional security features such as remote immobilization.

• Shock sensors

  Shock sensors are designed to detect any physical disturbance to the vehicle, such as a hard bump or impact. When a disturbance is detected, the shock sensor triggers the alarm. They offer an extra layer of security by monitoring the vehicle's surroundings and alerting potential break-ins. The sensitivity of shock sensors can usually be adjusted to reduce false alarms from minor disturbances.

Specification & Maintenance of Cheap Car Alarm System

Specification

Some of the most important specifications of car alarm systems are as follows.

• Shock Sensor

  Shock sensors, also known as impact sensors, are responsible for detecting physical blows to the automobile. They are designed to distinguish between minor events and serious attacks. They do this by measuring the intensity of the shock and the direction of the impact. When an assailant strikes or attempts to break into the vehicle, the shock sensor activates the alarm. They can be distinguished by their sensitivity, which can be adjusted according to the car's needs and the user's environment.

• Door and Hood Sensors

  Door and hood sensors are car alarm system components that detect unauthorized access through openings in the vehicle. Typically installed on the doors, these sensors monitor the status of the doors (open or closed). In the event of a breach, they trigger the alarm. Hood sensors operate similarly, detecting unauthorized access attempts through hood openings. Together, door and hood sensors provide comprehensive protection by alerting the owner to potential breaches in real time.

• Glass Breakage Sensor

  A glass breakage sensor listens for the unique frequency sound of breaking glass. It is strategically placed inside the vehicle, usually near windows and windshields. When the sensor detects the sound of breaking glass, it activates the alarm, warning the owner of a potential break-in. These sensors enhance a car alarm system's security by providing an additional layer of protection. They can also be combined with other sensors to create a more complete alarm system.

• Tilt Sensor

  A tilt sensor in a car alarm system detects unauthorized attempts to tow, push, or otherwise move the vehicle without the owner's consent. It continuously monitors the vehicle's position and orientation. If the car is tilted or moved in a manner indicating an attack, the sensor activates the alarm. This feature is particularly useful for protecting against theft of the whole vehicle. It warns the owner of potential theft attempts and prevents the car from being moved without permission.

Maintenance

To keep a car alarm system in good condition, here are some maintenance tips.

• Regular Inspection

  The first step in maintaining a car alarm system is inspecting it regularly. It is necessary to check whether the control unit, sensors, wiring, and other components are in good condition.
